The reaction of boron trichloride with alcohols was reported in 1931, and was used to prepare dimethoxyboron chloride, B(OCH 3) 2 Cl. [3] Egon Wiberg and Wilhelm Ruschmann used it to prepare tetrahydroxydiboron by first introducing the boron–boron bond by reduction with sodium and then hydrolysing the resulting tetramethoxydiboron, B 2 (OCH 3) 4, to produce what they termed sub-boric acid.

Some representative reactions showing 1,2-addition of diboron tetrachloride to hydrocarbons. Some of these reactions can also be carried out under more forcing conditions with diboron tetrafluoride. Tetrahalodiboranes can add to unsaturated hydrocarbons. Schlesinger et al. published 1,2-additions of B 2 Cl 4 to ethylene and acetylene. [16]
Barium borate is an inorganic compound, a borate of barium with a chemical formula BaB 2 O 4 or Ba(BO 2) 2. It is available as a hydrate or dehydrated form, as white powder or colorless crystals. The crystals exist in the high-temperature α phase and low-temperature β phase, abbreviated as BBO ; both phases are birefringent , and BBO is a ...
